Skateboard apparatus with gripping frame

Abstract

A skateboard-type sports apparatus has a frame forming a grip for the user and provided internally with a standing surface beneath which a pair of roller elements can be provided. The roller elements are rotatable in respective holders which can be rectangular frame members pivotally mounted on the frame so that a pin and an eyelet on opposite sides of each member define a pivot line for the roller. The rollers can thus pivot in planes substantially perpendicular to a central plane of the frame.

I claim: 
     
       1. A sports apparatus comprising: a generally annular frame which can be moved on a bearing surface and having a central plane of the frame;   two roller elements accommodated on the frame and having bearing axles and mounted on said frame; and   means receiving said roller elements for rotation about said bearing axles and pivotable relative to said frame in a plane approximately perpendicular to the central plane of the frame, said frame being constructed on its inside with a user-standing area, said means receiving said roller elements comprising two bearing devices for the roller elements, in which the roller elements are supported and which are pivotable with respect to the central plane of the frame, each of the bearing devices being a bearing frame member formed on one side with a pin which projects into an associated recess formed in the frame, and on an opposite side with an eyelet which is traversed by a bolt fastened to the frame, a spring member being arranged between the bolt and the bearing frame member.   
     
     
       2. The sports apparatus defined in claim 1, wherein said bearing frame member is constructed as an approximately rectangular frame having side bars in which the roller elements are supported and from whose cross bars the pin and the eyelet project. 
     
     
       3. The sports apparatus defined in claim 1 wherein said spring member is formed by at least one elastically deformable sleeve. 
     
     
       4. The sports apparatus defined in claim 3 wherein the sleeve is formed with grooves on its outer surface. 
     
     
       5. The apparatus defined in claim 1 wherein said pin forms an acute angle of preferably approximately 60° with a central plane of the bearing frame member. 
     
     
       6. The sports apparatus defined in claim 1 wherein the standing area forms an acute angle of 5° to 20° with the central plane of the frame. 
     
     
       7. The sports apparatus defined in claim 1 wherein a connecting line between the pin and the eyelet forms an acute angle of approximately 30° with a user-standing area formed in said frame along an inside thereof above said roller elements. 
     
     
       8. The sports apparatus defined in claim 1 wherein said roller elements are rollers. 
     
     
       9. The sports apparatus defined in claim 1 wherein said roller elements are wheels.
